Based on the list price for the CS100 aircraft, the firm order contract is valued at around $309 million US, and could increase to $636 million US if the five options are exercised.

PrivatAir was founded more than 30 years ago and operates a large fleet of commercial and business aircraft to provide private charter and private airline services.

Its specialized services include exclusively business class flights on behalf of several major network airlines.

As a superb example of the versatility of the world's only all-new aircraft in its segment, the CSeries aircraft acquired by PrivatAir will be delivered in an all-business class configuration.

"The CSeries aircraft represent cutting-edge technology and are true 21st century jetliners," said Greg Thomas, president and chief executive officer, PrivatAir.

"The CS100 jetliner is very well suited for our route expansion plans and we look forward to introducing this very modern aircraft to our fleet."

Guy C. Hachey, president and chief operating officer, Bombardier Aerospace, said: "The CSeries aircraft program keeps growing and we have now announced our 11th customer.”

He added: "The CSeries family of aircraft is designed for operational flexibility and many airlines around the world, like PrivatAir, are becoming aware of how the aircraft can meet their future plans. Our global push, as well as the superior performance benefits of the CSeries aircraft, will ensure that Bombardier will capture a significant portion of the 100- to 149-seat market segment over the next twenty years."

Philippe Poutissou, vice-president, marketing, Bombardier Commercial Aircraft, said: "Included among the 11 customers that have selected the CSeries aircraft are major network carriers, national carriers, premium airlines serving city center airports, a low cost airline, leasing companies and now, with the order from PrivatAir announced today, a full-service provider to airline partners.”

Poutissou said: "This diversity of customers speaks volumes about the flexibility of the CSeries family of aircraft to meet air transport requirements worldwide."
